Comprehension: (Q. 60 to 61)
\( \mathrm{P} \)
If a man has a velocity varying with time given as \( v= \)
W \( 3 t^{2}, v \) is in \( \mathrm{m} / \mathrm{s} \) and \( t \) in sec then:
Regarding acceleration of man choose the correct option(s):
(1) Acceleration of man after \( t=3 \) second is 18 \( \mathrm{m} / \mathrm{s}^{2} \)
(2) Average acceleration of man during \( t=0 \) to \( t=3 \) seconds is \( 18 \mathrm{~m} / \mathrm{s}^{2} \)
(3) Average acceleration of man during \( t=0 \) to \( t=3 \) seconds is \( 9 \mathrm{~m} / \mathrm{s}^{2} \)
(4) Acceleration of man after \( t=3 \) second is 12 \( \mathrm{m} / \mathrm{s}^{2} \)
